Folding top cover structure of fire fighting truck

Abstract

The invention discloses a folding top cover structure of a fire fighting truck, which belongs to the technical field of fire fighting trucks. The fire fighting truck comprises a compartment body, and a compartment cavity is provided with an upper long edge and an upper short edge. The folding top cover structure comprises a group of linear bearings, a sliding guide rod, a group of top cover folding linkage mechanisms, a first-wing top cover and a second-wing top cover, wherein the group of linear bearings are fixed to one upward side surface on the upper long edge of the compartment cavity at intervals; the sliding guide rod is matched with the group of linear bearings, and a group of guide rod seats are fixed on the sliding guide rod; the group of top cover folding linkage mechanisms are connected with one side surface, facing to the compartment cavity, of the upper long edge of the compartment cavity at intervals; one side of the first-wing top cover in the length direction is fixed with the group of guide rod seats, and the other side of the first-wing top cover is hinged with one side of the second-wing top cover in the length direction; and the other side of the second -wing top cover in the length direction is connected with the group of top cover folding linkage mechanisms. The folding top cover structure of the fire fighting truck has the advantages that the compartment cavity can be covered for protection or opened rapidly, and the fetch and application of equipment in the compartment cavity cannot be interfered when the compartment cavity is opened.
